Is this an indent?

Can someone tell me if this is positive or an indent? I’ve only got clear positives before. Sorry for my dirty mattress, I’m washing my sheets LOL. Hubby and I have been pulling out since I got my Mirena out on March 3rd. I know it’s not effective, we will be blessed either way. I just wanna know if it’s positive or not. I should have a period in two days. The only reason I tested was because I craved a burger. I don’t like burgers. No other symptoms.
